Rainbow Oppenheimer-Snyder collapse and the entanglement entropy production
Michał Bobula, Tomasz Pawłowski
The dust ball collapse is studied in the context of the "rainbow metric" approach (where the matter content is supplemented with a scalar field perturbation) to the Oppenheimer-Sny…
Regularizations and quantum dynamics in loop quantum cosmology
Maciej Kowalczyk, Tomasz Pawłowski
One of critical components of Loop Quantum Gravity (LQG) and Cosmology (LQC) -- Thiemann regularization procedure is non-unique. Different choices of particular prescriptions lead…
Rainbow Black Hole From Quantum Gravitational Collapse
Aliasghar Parvizi, Tomasz Pawłowski, Yaser Tavakoli +1
Quantum evolution of a scalar field's modes propagating on quantum spacetime of a collapsing homogeneous dust ball is written effectively, as an evolution of the same quantum modes…
Quantum fluctuations and semiclassicality in an inflaton-driven evolution
David Brizuela, Tomasz Pawlowski
A semiclassical description of quantum systems is applied to probe the dynamics of the cosmological model of an inflationary universe with quadratic inflaton potential, described i…
Challenges in recovering a consistent cosmology from the effective dynamics of loop quantum gravity
Andrea Dapor, Klaus Liegener, Tomasz Pawłowski
We reexamine a set of existing procedures aimed at recovering the effective description of the dynamics of LQG in the context of cosmological solutions. In particular, the studies…
Emergent de Sitter epoch of the Loop Quantum Cosmos: a detailed analysis
Mehdi Assanioussi, Andrea Dapor, Klaus Liegener +1
We present a detailed analysis of a quantum model for Loop Quantum Cosmology based on strict application of the Thiemann regularization algorithm for the Hamiltonian in Loop Quantu…
